BackStory call for pitches

December 21st, 2012 marks the supposed end of the Mayan Long Count calendar, and some are forecasting the end of the world. So, why not spend the end times looking back at all the good times we had… worrying about the end times. On this episode: moments when we thought it was all over. We'll try to figure out why certain Armageddon scenarios pop up again and again, and what they've told us about American hopes and fears through the centuries. Freak storms, war, supernatural predictions, technological crises – send us stories of pending world doom and what people made of them at the time.
